The Help editor allows you to edit an additional lightbox popup page to contain any other information to assist the user in completing your course. It can be accessed via the Help button in the Tools tab.

Despite the Help label, this page can actually be edited just like any other page within the course, and whatever content you want to place in it is entirely up to you.
When the course is played, the Help window is accessed by clicking the Help button in the footer (if it is enabled).
